GEORGE FRANCIS MYERS, OF BUFFALO, NEW YORK, ASSIGNOR TO SUBMARINE ARMS CORPORATION, OF NEW YORK, Y.

TORPEDO.

To all whom it may concern:

. Be it lsnown that I, GEORGE FRANCIS Mvn'ns, a citizen of the United States, and residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Torpedo, of which the following is a specification.

This invention relates to an improvement in marine vessels, commonly known aS submarines, but having as its principal characteristic such form and dimensions that it can, and is primarily intended to be readily inserted and projected from a torpedo firi tube such as is generally carried by nava vessels and it is closely allied with that class of automatically controlled weapon (carrying an explosive charge and projected from a launching tube) known as a torpedo to the extent stated, and in addition has an independent dirigibility and functional action not possessed by the automobile torpedo and is capable of a far greater range of action than that weapon is capable of, even to the extent of returning to its base or starting point after having performed its mission.

After having been launched itmay be stopped, started or reversed; it may be deviated from its straight course, 6r dive, rise,

maneuver, deliver its explosive charge, reconnoiter and return to its base to receive another charge if desired. i

In acquiring this increased adaptability and efliciency of my invention over the automobile torpedo I have associated with the vessel proper certain combinations of elements variously placed and functioning under the control of a human operator, having a compartment for his occupancy, and if the.

hull be made large enough an assistant or associate operator may be employed therein;

all of which is herinafter fully described in detail and illustrated by the accompanying drawings, in which Figure l is a perspective view of my invention as it would appear in use after leaving the firing tube; Fig. 2 a front elevation; Fig. 3 a rear elevation; Fig. 4 a cross-sectional view taken at AA Fig. 2; Fig. 5 a cross-sectional view' taken at BB Fig. 2; Fig. 6 a cross section taken at 0-0 Fig. 5; Fig. 7 a cross section taken at DD Fig. 5; Fig. 8 a

1 i a shell or hull, having an outline or form similar to the automobile torpedo now in general use. but with the interior prefor compartments, 2, 3 and 4, separated by bulkheads 5 and 6. The forward compartment 2 contains preferably a group of projectiles 7 and 8 contained in tubes 9 and 10, these projectiles being preferably of different sizes for purposes 7 hereinafter explained. The intermediate compartment 3, havin a hatch 3 conveniently located, is provi ed for the operator and he is shown in Fig.

56 and 58 with the various manipulating .control elements within easy reach.

The after compartment 4 contains the ropulsion motor, herein shown as a gaso ene engine driving the oppositely revolving propellers 12 and 13 as is usual in machines of this class, 12 rotating by the control shaft the motor and the propeller 13 being attached or mounted upon the hollow shaft 15 and rotated in the opposite direction by means of bevel gears 16, thus to equalize the torque, or tendency to twist or rotate the torpedo.

It is apparent that in a vessel of this character wherein the operator is wholly inclosed within the hull there must be some means by which visibility of surroundin or location is afi'ordedthe operator that 0 may work intelligently such as the periscope commonly used by submarines, which projects vertically therefrom. But it is equally obvious that a perisco e as thus constructed would "not .be applica' 1e to. a torpedo form of submarine vessel adapted to be firedcfrom features of vertical sight and fire enabling the operator to observe conditions above the torpedo and protect himself from 4 ,a1rcraft'. A description of the construction the operator is a recess 17, formed in the hull At the rear end of this shown in Fig. 13, there .or shell, having parallel sides 18 and a plain closure 19 at its forward end and a stepped closure at its rear end 20. Attached to the underside of this recess is a tube 21 extend: ing from the stepped end forward and 'beyond the end 19 at which end thereis anopening 22 pointing downwardly and having a ninety-degree reflecting medium 23. tube which is closed, is another such me-. dium 24. The rear end of the tube forms an- L with its short length 25 projecting vertically therefrom. Within this yertical portion is suitably mounted for rotation a short length of tubing 25' having a retainer 26 and a gear 27 formed at its /lower edge. 'Its upper edge is serrated as at 28. Secured within is a transparent disk 29 whose upper surface coincides with the lower edge ofthe serration. Secured to the upper surface of the tube 21 is a bearing 30, in which is mounted shaft 31 carrying pinion or gear 32 which engages gear 27. The shaft extends through the entire length of the tube and projects through the forward end carrying a hand wheel 33. Pivotally mounted, adja cent to the vertical section of the tube 25 by means of binge 34,. is a tube 35. Within this vtube is another tube 36. which has a serrated tube 36 is ,secured a end 37 corresponding of the short tube wit tube 36 is in an erect to the serrated edge 28 which it engages when position. Within the transparent disk 38. Tube 35 carries a structure formed of a" casing 39 having. a form such as would present the least resistance to forward movement closure 41,; the bottom being and leave as little disturbance as possible in its wake having a top closure 40 and bottom at aposition properly distant from the huge 34 to cause bottom 41 to rest squarely'upon, and entirely in contact with, step 42 of thefperiscope recess when the periscopes movable member is raised to.a vertical position.- In Fig. 10 it is shown that tube '36 extends beyond the tube 35 at its upper end. 'Secured to tube 36 is the cap 43 having an opening 44 covered by glass 45. A ninety-degree reflecting medium 46 is positioned in the cap at the junc-- v ture of the axis of hole 44 and tube 36. In

Fig. 4 is shown a-mirror 47 suitably mounted toreflect light from reflector 23 m tube 21 to the operators eye; Thus it willbe evident that there is clear vision from his eye to the outside of the torpedo when'theperiscope is vertical, hrough reflectors 47, 23', 24, 46 and the hole/44.. Referring to 16, 17 and 1s, 43'

trolled by is a transparent cap se- .cured to stationary tube 35. The mirror secured in frame 46' is pivotally mounted" on bearings 48 formed on the revolving tube 36. 49 is a pinion carried upon the mirror 71; shaft and is adapted to engage segmental rack 56' formed on the end of tube 35, for rotating the mirror upon its free shaft, the mirror remaining in its inclined position when not engaging the rack as its rotation is opposed by a frictionpressure-on its bearings. When the torpedo is not in active service or is within its firing tube the periscopes movable member lies within the recess 17'relug 48 located upon the top closure 40 of the periscope casing and adapted to engage the projecting stem 49 of the armature having an elastic opposition of electromagnet or solenoid 50 connected with an electric circuit, and which'is mounted upon the stationary member of the periscope and is cona push button 51 conveniently placed within reach of the operator. Located within the recess 17 is a leaf spring 52 adapted to be held compressed by the folded and latched periscope member. The spring possessessuflicient power and range to throw theperiscope out of and above the recess 17, its further movement to a vertical position being accomplished preferably by the pressure of the water as the vessel travels forward. In.its vertical or active position the lower closure 41 rests upon and in close con tact withstep 42' of the recess 17 and serrated ends 28 and 37 of tubes 25' and 36 are engaged for mutual rotation. The water pressure may be sufficient to retain the periscope vertically, but means is also provided for locking it thus, which may be necessary in traveling astern, which consists'preferably of a magnetic device as shown in Figs. 4 and 13, where 53 is a pair of electromagnets secured within the hull and at their upper ends to the step 42 of the recess 17. 110 Lower closure 41 being composed of a suitable metal will be held, as an armature, against the poles of the magnets. A controlling switch 54 in circuit with these magnets .is located within convenient reach of 115. the operator. It will now be apparent that by this novel construction a periscope is provided that'can be folded to a positionwithin the outline of the hull for the purpose of allowing its entry into the torpedo firing tube. 120 My folding periscope forms part of a combination ofelements which I employ to function in other important features of fny invention which will now be set forth.

. In illustrating my invention I have em- 125 ployed an internal combustion. motor or motor using liquid fuel, for propulsion, or

it maybe any form of motor requiring a supply of air or its equivalent to ..promote its operation. This could be supplied from a 130 ing described means to supply air to the engine asrequired during the consumption of the entire fuel supply: 55 is the motor supplied with fuel from the tanks 56 through the pipe 57. 58 is a flask of stored air resting upon the bottom of the operators compartment having a pipe 59 communicating with the after compartment 4. Air from the flask is controlled by a pressure reducing valve 60 and a valve 61 which is shown in an open position by magnet62 against the action of spring 62 in the manner shown in Figs. 4, 5 and 12 Air from outside the vessel is also supplied to the after compartment and motor, alternating with the air in flask 58, as the upper end of the periscope submerges or emerges from the water. To accomplish this I utilize the space 63 as an air passage having an outlet 63 in the top 40, provided with a hinged cover 64:. Communication between this space and the afterbody is established in the manner shown in Fig. 13 thus: Ahinged valve 67 is located upon the step 42 of the recess 17 opening into the pipe 68 which terminates in the after compartment 4 and .from which depends drip pipe 69. A valve 70 opens inwardly to the space 63. Both of these valves are normally closed by their springs as shown until the periscope is brought to its operative or active position in which case the projection 71 engages with valve lid 70 causing it to open, and projection 72 operates similarly upon valve lid 67 thus opening up the passage. The valve lid 64 is connected by link 65 to armature 66, which is controlled by electro-magnet 7 3, opposing the action of spring 74. Conveniently located within reach of the operator is the switch 75. Fig. 12 shows the method of connecting the valves 64 and 61, the flask controlling magnet 62 and the controlling switch 7 5, which is accomplished by using but two wires 76 and 77 and a grounded connection 78 and 82. Winding of magnet 73 is connected or grounded at one terminal to the periscope casing as 78 and its other terminal to wire 76 connecting with female member of plug switch 79, the male member 80 of which is connected to one end of winding of valve magnet 62. The other terminal of this magnet is connected to the source of energy 81 which is in turn connected to switch and through same to the ground connection at 82. Intermediate the switch 75 and source of energy 81 is a connection 83 from which is led a wire 77 through scope casing for firing skyward as a protection against air craft and to this end I show in substance an arrangement by which this may be accomplished. 88 is a gun of any suitable design secured within the'casing 39 with its muzzle passing through the closure 40 and covered by the flap orcover 89. 90. is an electromagnet with its circuit and source of energy 91, shown in diagrammatic form, with switch 92 which would be placed within the operators compartment; The armature 93 is connected by link 94 to the gun muzzle cover 89 and also to a rod passing downwardly through guide 95 to a proper position for operating trigger 96 after cover 89 has opened sufficiently to clear the path of the projectile. A spring 97 connects the armature with the top old sure 40 ofthe casing tending to keep the muzzle cover closed when armature 93 is not energized thus preventing water from entering the gun.

In the forward compartment 2 the projectiles 7 and 8 are shown within their firing tubes 9 and 10, the larger one being placed underneath in order to have the center of gravity low as possible, with pipes, as 98, connecting each one with the bus-pipe 99, passing through bulk-head 5 to the flask 58. Each pipe 98 has a valve 99 with stem passing through the bulkhead and terminating in a handle 100. In the forward end of the hull and in line with, each projectile are hinged covers 101 and 102. The large one 102 carries an electric head light '103 in casing 104 which is furnished with lens 105 covering the opening 106 in-the cover. A switch or push button 106 in the operators compartment controls the head light. Just 110 above the large cover hinge is a tube 107 having a lens covered opening at 108 in its forward end and its other end passing through the bulkhead. It there forms an L 109 passing downwardly center-line of the hull as shown in Fig. 7 where it again forms an L 110 and terminates within a convenient distance from the operators eye. Within the said Ls are se-' cured ninety-degree reflecting members. By 120 this arrangement a view of thesurroundings forward of the torpedo can be had by the operator. 111 'is a ballast tank-having its rear end opening to the outside of the hull by pipe 112,which has a controlling'valv e 125 113 operated by electromagnet 114 andcontrolled by electric push button 114. At the forward end of the tankis a similar valve 115, which is normally closed and controlled by electric push button 116, operated by 0 to one side of the 115 magnet 116 controlling air from the flask 58 through pipe 117 to the'tank 111. The aropposing the magnetic attraction.

The steering of the torpedo both vertically and horizontally is accomplished in the usual manner common to this class of machines by the use of vertical rudders 118 .and horizontal rudders 119 having connecting cables 120 and 121. Th actuating system for controlling the rudders may be of any of the matures of these valve magnets have springs I well known devices .for this purpose as practised in the submarine and torpedo art.

, head.

The operation of my invention is as follows:

The operator takes up his position within his compartment lying upon the pad and. 1 inserting his head in the rest strap. With the periscope folded and latched within its recess the torpedo "is inserted in the firing tube from which it' is launched. As the machine is entirely self-contained and independently dirigible the vessel carrying the firing tu e may not necessarily aim at the target and may fire several torpedoes from difl'erent. sides, thus causing no delay or trouble inturning large vessels especially when they carry submerged torpedo tubes.

' Having emerged fromthefiring' tube the operator starts his propeller engine and presses electric push button 51 releasing the eriscope which rises to its vertical position. f at the start the torpedo is at; a depth where the top of the periscope is submerged the wave actlon or pressure of the water will I close the valve64 preventing an inrush of water. A small; portion may enter during the valve action but this will bedrawn through the drippipe '69 and expelled by proper means such as a bilgepump. Upon the closing of valve 64, stopping olf the out-. side air supply to the englne, air will be automatically released from the flask 5 8 Y which will continue until the emerges. Thus a constant a ternating supply of air will be furnished the motor. The closing of valve 64 and opening of valve 61 supplying air fromthe flask 58 to the water may be performed by closing switch' 7 5 peri-scope again when desirable. The operator Wlll now contin'ue his course whether at surfaceor submerged. If he desires to-submerge 4 he presses electric push button 114:" which causes magnet 114 to open the valve 113 be located within the torpedo or and fuel therefor comprising1 allowing water to enter the tank 111 causing the vessel to descend to adepth governed by the increased weight proportional to the amountof water admitted. To ascend the; button 116 is pressed, together with button 114', allowingair from the flask 58 to expel 'the water thereby'increa-sing the buoyancy of the torpedo and causing it to rise.

With

the periscopeabove water the operator may observe the surrounding condition by revolving the hand wheel33. In turning the mirror from G to H, J or K, Fig.r17, it remains at a forty-five degree inclination. When desiring to look above the torpedo he turns tube 36 until the segmental rack rotates the mirror sufliciently to bring it to a vertical position as in Fig. 18. This will enable him to see above and direct the time of firin the periscope n.

Wheri submerged the operator may ob; serve'objects ahead such as ex losive or other submarines through tu 107 which forms a horizontal periscope and is assisted by the. illumination of the headlight controlled by the switch in his compartment.

1 When the torpedo is within striking distance of the target the operator, selecting the $129 of projectile most suited to accomplish I the desired result from an economical standpoint, pulls the corresponding valve lever controllingthe expelling medium, which fires the projectile from its tube through the forward door. j
